CHARLOTTE, N.C. — Reince Priebus was reelected chairman of the Republican National Committee on Friday, overcoming divisions and tensions in the party as he pledged to remake and restore the Republican brand before the congressional elections next year and the presidential race in 2016.

He was elected with near unanimity to serve a second term at the helm of the Republican Party. He allayed concerns from some party officials and activists about the outcome of last year’s elections and sought reelection without serious opposition.

‘‘We can stand by our timeless principles and articulate them in ways that are modern and relevant to our time and relatable to the majority of voters,’’ he said. ‘‘And that, I believe, is how we’ll achieve a Republican renewal.’’

The election here Friday during the annual winter meeting of the committee unfolded without the drama of two years ago when Priebus was elected after surviving seven rounds of balloting to overtake Michael Steele, the embattled party chairman.

Priebus, 40, a former chairman of the Wisconsin Republican Party, delivered a blunt message to the party during his acceptance speech. He said that the party needed to rebuild across the country and not simply focus on the same states that are at the center of every presidential election.

‘‘There is one clear, overriding lesson from November: We didn’t have enough voters,’’ Priebus said. ‘‘We have to find more supporters. We have to go places we haven’t been, and we have to invite new people to join us.’’

Priebus said the party needed to improve its technology to compete with Democrats but also focus on returning to the basics of building a strong get-out-the-vote operation. He did not talk specifically about the divisions inside the party over fiscal and social issues.
